Mark,

Take a look at:

  getOption("editor")

and see what it returns.  More than likely "EMACS" from what I see above.

It should be in all lower case. That is 'emacs'.

Take a look at your .Rprofile or perhaps at the 'EDITOR' or "VISUAL'
shell variables to see where you have this set and edit accordingly.
See ?edit for more information.

Enjoy the book. My copy came just before I left for useR! and I have not
had a chance to read it yet.

Regards,
